Climbers who discovered the body of Mallory on Mount Everest have sent a tissue sample for testing to prove conclusively the remains were those of the British explorer lost in 1924, an expedition official said on Tuesday.
ENGINE RUN-ON, DIESELING -- RO-101. DIESELING, that nasty tendency of an engine to continue to run on, coughing and sputtering, after the ignition is turned off and there is no more spark. Run-on by dieseling is caused by fuel in engine igniting without spark. Possible explanations: a.) Running winter fuel in warm weather.
Like many other engines, a rocket produces thrust by burning fuel. Most rocket engines turn the fuel into hot gas. Pushing the gas out of the back of the engine makes the rocket move forward. A rocket is different from a jet engine. A jet engine requires oxygen from the air to work. A rocket engine carries everything it needs. That is why a rocket engine works in space, where there is no air.
